The rules implemented by the Transportation Security Administration (TSA) regarding liquids are implemented to keep passengers safe while on airplanes. These rules include limits on the container size of liquids passengers can take on board a flight. Many medications are contained in bottles larger than the size deemed safe by the TSA, so the administration has set up a program to meet the needs of passengers with diseases or medical conditions who need to fly with their medications. Screening requirements still apply, but travelers needn't worry about carrying prescriptions on board airplanes.

Step 1.

Pack your liquid prescription drugs in a clear, quart-sized, zip-lock resealable bag inside your carry-on luggage, if the drugs fit. If the drugs do not fit, simply place the container inside your luggage. Liquid medications are exempt from the Transportation Security Administration's rules regarding container size.

Step 2.

Pack your pills inside your carry-on bag. TSA allows you to take pills on board but requires that a security officer screen them.

Step 3.

Let a TSA officer know if you are carrying a liquid medication in a bottle larger than the authority's allowed limit. Passengers carrying medications in containers falling within TSA's size guidelines don't need to declare their drugs. Allowable container sizes may change, so contact TSA for up-to-date information.

Step 4.

Allow a TSA officer to scan medications contained in bottles that exceed allowable size limits. The scan will assure the officer that the liquid doesn't contain materials potentially hazardous to other passengers. You can ask that the security officers visually inspect the medication instead of scanning it.

Step 5.

Show TSA a letter from your doctor that explains why you need the medication. TSA does not require this step, but the administration recommends it to expedite the screening process.

Step 6.

Carry only prescriptions that have your name on them. TSA officers will compare the name on the medication labels to the name on your boarding pass. If the names don't match, the TSA officer will ask why.
